ECU reset with engine warmed up or cold?

gh0st3794 · 03-21-2010, 01:15 AM

After I perform an ECU reset I usually start the car and let it idle for a bit, then go for a drive. Does it make a difference if I do the ecu reset/drive cycle with the engine cold or already warmed up?

Doesn't matter. All you're doing is clearing the fuel trims. It takes some drive time for them to re-adapt..
